Introduction to the Development of Titanium Metal Injection Molding MIM and Its Application in Smart Watches

Aug 07, 2023

In recent years, outdoor sports have emerged, and sports smart watches have become increasingly popular among people. Major smartwatch manufacturers not only innovate in the sports functions of smartwatches, but also have made many attempts at watch materials. Titanium and titanium alloys are favored by the smartwatch industry for their lightweight, high strength, corrosion resistance, allergy resistance, and beautiful appearance.

1、 Development status of MIM for titanium and titanium alloys

The injection molding technology of titanium began in 1988 and was applied in the mid-1990s. At present, pure titanium powder, Ti-6Al-4V, TiAl, Ti Mo Al, and some other titanium based material powders have been successfully manufactured using injection molding technology. Japan's Injex titanium MIM products have been applied in luxury goods such as golf heads, automatic cars, medical machinery, dental implants, and watch cases, straps, and buckles. Titanium MIM molding has the characteristics of easy alloy composition control, high raw material utilization, simple production process, and high production efficiency.

There are still many problems in the development of MIM for titanium and titanium alloys, mainly including:

Low oxygen spherical titanium powder has a high price, and oxygen pollution makes it difficult to obtain nanoscale titanium powder;

The most practical process for selecting and removing adhesives is currently EBS wax, but it requires vacuum or argon environment removal, which is costly;

Removal of gap elements, etc.

The preparation of low oxygen, low cost, and fine-grained spherical titanium powder is the main direction of development for titanium and titanium alloy powder. The titanium powder prepared by atomization technology has small particle size, high sphericity, low oxygen content, and the ability to produce on a large scale with low cost. It is currently the main method for producing high-performance spherical titanium and alloy powders. At the same time, developing a new and efficient binder system for titanium alloy MIM, optimizing mixing, degreasing, sintering processes, and injection parameters are the key to preparing low-cost and high-performance titanium alloy injection molded parts.
